The single supplement can add 125-200% to your fare. Here is why it exists, which cruise lines have real solo cabins, which have none at all, and how to sail alone without paying for an empty pillow.

What actually happens on embarkation day, why trying to board first is a waste of your vacation, what belongs in your carry-on, and how to start the week the way you meant to.

Find the best cruise lines for adults, from genuinely kid-free ships to lifestyle charters and adult-only retreats. Compare age restrictions, included perks, extra costs, and the fine print before booking.
